Rocky was referred to a specialist here in Australia and they have confirmed that he has cancer. Unfortunately there isn't anyhing they can do and because of his age they don't think he will be strong enough to go through the treatment.
His leg is now very swollen and is having alot of difficulty walking.

I'm so sorry for your loss. Rocky lived a full Boxer life, I'm sure at the age of 12 he experienced a lot of life, love and happiness. He is healthy once again running in fields of green with other pups.
Take Care,
Christy
